"Tianhe Core Module" yakatangwa zvinobudirira!Nzira yekugadzirisa sei dambudziko rekushandisa simba pachiteshi chemuchadenga uye zvakachengeteka sei?

Musi wa29 Kubvumbi, iyo Yakareba Kurume 5B Yao-2 inotakura roketi yakatakura chiteshi chemuchadenga Tianhe core module mumhepo zvakabudirira paWenchang Space Launch Site muChina.Ino ndiyo imwe nguva ine nhoroondo munhoroondo yekubhururuka kwemuchadenga kwenyika yangu zvichitevera kubudirira kuzere kwendege yekutanga yeLong March 5B inotakura roketi muna Chivabvu 2020.

        China Manned Space Station, inodaidzwa kunzi China Space Station kana Tiangong Space Station, inzvimbo yerabhoritari yemuchadenga ine maChinese maitiro akaunganidzwa mukutenderera.Kureba kwe orbital kwechiteshi chemuchadenga makiromita 400-450, kona yekurerekera i42-43 madhigirii, chiteshi chemuchadenga chinonzi "Tiangong", uye chitundumuseremusere chinotakura zvinhu chinonzi "Tianzhou".Iyo China Space Station inoshandisa matatu-kabhini "Tianhe Core Module", "Wentian Yekuedza Module" uye "Mengtian Yekuedza Module" seyakanyanya kurongeka.

        Iyo Tianhe core module ndiyo yekuraira uye nzvimbo yekutonga yeramangwana nzvimbo chiteshi.Hupenyu hwezuva nezuva hwevachadenga huchaitwa pano, uye kumwe kuyedza kwesainzi yemuchadenga uye hunyanzvi hwekuyedza huchaitwa pano.Kuitira kuti hupenyu hwenguva refu hwevachadenga vari muchadenga hugadzikane, iyo core module inopa inosvika makumi mashanu cubic metres enzvimbo kuti vazivi vemuchadenga vashande uye vararame.Mukuwedzera pakuvandudza nzvimbo yekurara, nzvimbo yakakosha yehutsanana uye nzvimbo yemitambo yakawedzerwawo.Uye zvakare, WIFI inogona kubatana neInternet mucore cabin.Nehurongwa hwakakura kudaro, kudiwa kwemagetsi kunokwidziridzwa zvakafanana kusvika kanenge katatu iyo ye "Tiangong No. 2", iyo inoda simba rakasimba rekudzivirira.

        Muchadenga, iyo chete sosi yesimba reiyo core module isimba rezuva. Naizvozvo, iyo Tianhe core cabin yakashongedzerwa maviri maviri enzvimbo yakakura-yenzvimbo solar cell mapapiro, ine imwe bapiro nzvimbo ye67 square metres.Inoshandura simba rezuva kuita simba remagetsi munzvimbo yakavhenekerwa kuti ishandiswe muimba yose, uye panguva imwe chete inochengetedza simba rebhatiri kuti rishandiswe kana core cabin ichibhururuka ichienda kunzvimbo ine shaded.Kukwanisa kugadzirwa kwemagetsi kweaya maseti maviri emapapiro esolar cell kwakapfuura 18,000 watts, kudarika chero chitundumuseremusere chakapfuura muChina.

Iyo yebapiro-imwe span yebapiro rezuva rebapiro re "Tiangong-2" inongova 3 metres, uye kuendeswa kwebapiro rimwe chete kwebapiro rebhatiri reTianhe core cabin kwawedzera kusvika 12.6 metres.Nzvimbo yekurodha yemotokari yekutangisa ishoma, uye vagadziri vakaisa mapapiro ebhatiri ezuva reakawanda-dimensional uye akawanda-nhanho kuendesa kekutanga muChina, uye dambudziko iri rakagadziriswa nehungwaru.Kubatsirwa nekushandiswa kwekatatu-junction gallium arsenide solar masero ane hunyanzvi hwekuita photoelectric shanduko inoshanda,ivo, pamwe chete neakakwirira-chaiwo simba re lithium-ion mabhatiri, vanoumba simba remagetsi sisitimu yekupa yakavimbika uye yakakwana isina kukanganiswa kugadzirwa kwemagetsi kwenzvimbo chiteshi..

Rimwe basa rakakosha reiyo musimboti kabhini solar bhatiri bapiro nderekuti bapiro rese rinogona kuparadzaniswa uye kutamiswa panguva yekutenderera.Tichifunga kuti solar cell mapapiro eiyo core cabin ichavharwa mushure mekupedzwa kwekuzotevera kwenzvimbo yekuvakwa kwechiteshi, izvo zvichakanganisa kugadzirwa kwemagetsi, mapapiro maviri esolar cell mapapiro anogona kupatsanurwa uye kutamiswa kunze kwekabhini nevazivi venyeredzi nemaoko erobhoti. , uye yakaiswa mumuswe weiyo yekuyedza kabhini yekuzovhurwa kunotevera.Pane truss, chiteshi chemagetsi chinovakwa patsva pane orbit kuti uone basa rekuwedzera simba pane orbit.

Chiteshi chemuchadenga chave chichishanda zvakadzikama kwenguva yakareba mukutenderera, uye vazivi vemuchadenga vanogara kwenguva yakareba.Kuchengetedzeka kwechiteshi ndiyo nyaya inonyanya kukosha.Kana chiteshi chemuchadenga chapinda munzvimbo ine mumvuri umo zuva risingakwanise kuvhenekerwa, bhatiri re lithium-ion rinoita basa rekusimbisa imba yese.Nzira yekuchengetedza sei bhatiri?

Vatsvakurudzi vakawana mhinduro mushure mekutsvakurudza kwenguva refu.Vakagadzira ahupenyu hurefu, hukuru-hukuru, kuchengetedzwa kwepamusorolithium-ion bhatiri rinosangana nezvido zvekushanda zvenzvimbo chiteshi.Bhatiri rinoshandisa ceramic diaphragm, iyo ine simba rakanaka rekudzivirira mukati mapfupi-circuits.Panguva imwecheteyo, zvinhu zvinodzivirira moto zvinoshandiswa mubhatiri pack kudzivirira bhatiri kubva pakupisa nekuda kwekupisa kwakanyanya.

Zvinonzi kune 6 seti yemabhatiri e-lithium-ion muchikamu chepakati chechiteshi chemuchadenga, imwe neimwe ine 66 masero mamwechete.Vatsvakurudzi vakagadzirawo yakangwara lithium bhatiri management system kuti iwane yakakwirira-chaiyo, yakakwirira-kuvimbika, uye yakakwirira-yakachengeteka lithium bhatiri yekuchaja kutonga.Iyo mitatu-nhanho yekudzivirira meshini inoshandiswa kana bhatiri richichaja, uye tembiricha yekutarisa inoitwa.Kana tembiricha yekuchaja yakakwira kupfuura iyo yakachengeteka tembiricha kukosha, bhatiri rinochajwa nekukasira.

Panguva yekushanda kwechiteshi chemuchadenga kweanopfuura makore gumi, vazivi vemuchadenga vanofanirwa kupota vachitsiva mabhatiri e lithium mu orbit.Nzira yekuona sei kushanda kwakachengeteka kwevazivi vemuchadenga pasina kukanganisa yakajairika magetsi echiteshi chemuchadenga?Vagadziri vakapa "double insurance" ye lithium bhatiri kutsiva oparesheni.The core compartment ine maviri magetsi emagetsi.Kana imwe chiteshi ichida kutsiviwa nebhatiri, imwe chiteshi inoshandiswa seyo huru magetsi.Mune yega yega chiteshi chemagetsi, kana bhatiri mune chero yuniti inoda kutsiviwa, iyo unit inodzimwa, uye maviri asara mayuniti anogona kuve nechokwadi chenguva dzose magetsi echiteshi ichi.

Uye zvakare, vaongorori vakaisa maviri akaenzana masegmented switch mu lithium-ion bhatiri module.Nekudzikisa voltage yebhatiri pack kusvika kune yakachengeteka voltage renji yemuviri wemunhu, inosangana ne36-volt kuchengetedza voltage inodiwa yemuviri wemunhu uye inodzivirira vanoongorora muchadenga mumunda.Kuchengetedzeka kwemunhu panguva yekugadzirisa njanji.

Mushure mekunge iyo core module yavhurwa zvinobudirira, mishoni inotevera ichave "Tianzhou II" inotakura zvinhu muchadenga, uye ipapo chitundumuseremusere chine munhu chichatangwa.Mushure me "Tianzhou II" docks ine core module, ichatakura vatatu venyeredzi.Iyo "Shenzhou XII" spacecraft ichapindawo muchikamu chekugadzirira kutanga.Kuvhurwa kweTianhe core module kwakavhura zviri pamutemo nhanganyaya yekuvakwa kwechiteshi chemuchadenga cheChina, uye yaivewo chiitiko chakakosha munhoroondo yekubhururuka kwechadenga kweChina.Yakaratidza kuti kuvakwa kwechiteshi chepasi chenyika yangu kwapinda padanho rekuita zvizere uye kwakaisa hwaro hwakasimba hwemisheni dzinotevera.
